Bootstrap 3 Classes List With Description - Bootstrap Cheat Sheet.txt

Every web developer should know how to properly code a responsive website. Bootstrap 3 is an ultimate
framework that learns you how to think when coding responsive websites and makes their creation much easier and faster.
When I was learning Bootstrap 3, I was looking for a simple list of basic Bootstrap 3 classes with description and there were none - only a few lists for Bootstrap 2, without any description, therefore pretty useless for my intentions.


Basic Bootstrap Classes
.container

sets fixed width to an element (which changes depending on a screen size to other fixed values, so it's still responsive) on all screen sizes except xs - on xs, the width is calculated automatically (this behaviour can be changed)
a fixed width responsive website should be wrapped in .container (or just the content without menu, whatever - it's up to you)
.container can't be nested!
.container-fluid

sets 100% width, margin-left and margin-right: auto, padding-left and padding-right: 15px
a full screen website should be wrapped in .container-fluid
.container-fluid can't be nested!
.row

creates horizontal groups of columns (which usually have width classes, see below)
must be within .container to ensure correct padding and alignment
only columns (block elements with width classes) may be immediate children of rows
sets margin-left and margin-right: -15px
.pull-right

.pull-left

sets float to either left or right
.center-block

sets margin-left and margin-right to auto
